Mines pretty easy - its a combination of words from Poe's poem "The Raven".

When I first got on the internet with AOL a bazillion years ago they required a username of course, and also of course my actual name and every variation of it had already been taken. So I started trying things like favorite tv shows, movies, ect... None were available and I was getting frustrated, so I tried "Raven" (favorite poem). It was taken too. I had it at that point and just threw "more" on the end of it ("quoth the Raven 'never more'") and the rest is history.

When I played baseball the coaches would call us by our last names, however they just called me by the first 3 characters of my last name, hos, pronounced like the Bonanza character Hoss. 13 was my jersey number, thus "hos13".
